In this paper, glacier and climate changes in Xinjiang during the past decades were comprehensively discussed based on glacier inventory data, individual monitored glacier observations, recent publications, as well as meteorological records. The results show that glaciers have been in continuous mass loss and dimensional shrinkage since the 1960s, although there are spatial differences between mountains and sub-regions, and the significant temperature increase is the dominant controlling factor of glacier change. The mass loss of monitored glaciers in the Tien Shan has accelerated since the late 1990s, but has a slight slowing after 2010. Remote sensing results also show a more negative mass balance in the 2000s and mass loss slowing in the latest decade (2010s) in most regions. -

Quantifying Trends of Land Change in Qinghai-Tibet Plateau During 2001–2015
remote sensing Article Quantifying Trends of Land Change in Qinghai-Tibet Plateau during 2001–2015 Chao Wang, Qiong Gao and Mei Yu * Department of Environmental Sciences, University of Puerto Rico, Rio Piedras, San Juan, PR 00936, USA; [email protected] (C.W.); [email protected] (Q.G.) * Correspondence: [email protected]; Tel.: +1-787-764-0000 Received: 1 September 2019; Accepted: 17 October 2019; Published: 20 October 2019 Abstract: The Qinghai-Tibet Plateau (QTP) is among the most sensitive ecosystems to changes in global climate and human activities, and quantifying its consequent change in land-cover land-use (LCLU) is vital for assessing the responses and feedbacks of alpine ecosystems to global climate changes. In this study, we first classified annual LCLU maps from 2001–2015 in QTP from MODIS satellite images, then analyzed the patterns of regional hotspots with significant land changes across QTP, and finally, associated these trends in land change with climate forcing and human activities. The pattern of land changes suggested that forests and closed shrublands experienced substantial expansions in the southeastern mountainous region during 2001–2015 with the expansion of massive meadow loss. Agricultural land abandonment and the conversion by conservation policies existed in QTP, and the newly-reclaimed agricultural land partially offset the loss with the resulting net change of 5.1%. Although the urban area only expanded 586 km2, mainly at the expense of agricultural − land, its rate of change was the largest (41.2%). Surface water exhibited a large expansion of 5866 km2 (10.2%) in the endorheic basins, while mountain glaciers retreated 8894 km2 ( 3.4%) mainly in the − southern and southeastern QTP. -
Teach Uyghur Project Educational Outreach Document
TEACH UYGHUR PROJECT EDUCATIONAL OUTREACH DOCUMENT UYGHUR AMERICAN ASSOCIATION / NOVEMBER 2020 Who are the Uyghurs? The Uyghurs are a Turkic, majority Muslim ethnic group indigenous to Central Asia. The Uyghur homeland is known to Uyghurs as East Turkistan, but is officially known and internationally recognized as the Xinjiang Uyghur Autonomous Region of the People's Republic of China. Due to the occupation of their homeland by the Qing Dynasty of China and the colonization of East Turkistan initiated by the Chinese Communist Party, many Uyghurs have fled abroad. There are several hundred thousand Uyghurs living in the independent Central Asian states of Uzbekistan, Kazakhstan, and Kyrgyzstan, as well as a large diaspora in Turkey and in Europe. There are and estimated 8,000 to 10,000 Uyghurs in the United States. The Uyghur people are currently being subjected to a campaign of mass incarceration, mass surveillance, forced labor, population control, and genocide, perpetrated by the Chinese Communist Party (CCP). About the Uyghur American Association (UAA) Established in 1998, the Uyghur American Association (UAA) is a non-partisan organization with the chief goals of promoting and preserving Uyghur culture, and supporting the right of Uyghur people to use peaceful, democratic means to determine their own political futures. Based in the Washington D.C. Metropolitan Area, the UAA serves as the primary hub for the Uyghur diaspora community in the United States. About the "Teach Uyghur Project" Education is a powerful tool for facilitating change. The goal of this project is to encourage teachers to teach about Uyghurs, and to persuade schools, and eventually state legislatures, to incorporate Uyghurs into primary and secondary school curriculum. -
Cenozoic Deformation of the Tarim Plate and the Implications for Mountain Building in the Tibetan Plateau and the Tian Shan

Dissertation Advisor: Mark C. Elliott Eric Tanner Schluessel The Muslim Emperor of China: Everyday Politics in Colonial Xinjiang, 1877-1933 Abstract This dissertation concerns the ways in which a Chinese civilizing project intervened powerfully in cultural and social change in the Muslim-majority region of Xinjiang from the 1870s through the 1930s. I demonstrate that the efforts of officials following an ideology of domination and transformation rooted in the Chinese Classics changed the ways that people associated with each other and defined themselves and how Muslims understood their place in history and in global space. -

This review first summarizes recent observed changes of Snow cover snow cover over the TP, including the relationship between the TP snow cover and that over Eurasia as a whole; Asian summer monsoon recent climatology and spatial patterns; inter-annual variability and trends; as well as projected changes in snow Climate change cover. Second, we discuss the physical causes and factors contributing to variations in snow cover over the TP, including precipitation, temperature, and synoptic forcing such as the Arctic Oscillation and the westerly jet, and large scale ocean-atmosphere oscillations such as the El Niño–Southern Oscillation (ESNO), the Indian Ocean dipole, and the southern annular mode. -

Wang <[email protected]>; S. Hou <[email protected]> ABSTRACT. Western Kunlun Mountain (WKM) glaciers show balanced or even slightly positive mass budgets in the early 21st century, and this is anomalous in a global context of glacier reduction. However, it is unknown whether the stability prevails at longer time scales because mass budgets have been unavailable before 2000. Here topographical maps, Shuttle Radar Topography Mission and Landsat data are used to examine the area and surface elevation changes of glaciers on the WKM since the 1970s. Heterogeneous glacier behaviors are observed not only in the changes of length and area, but also in the spatial distribution of surface elevation changes. -

The topography of China ranges from the highest elevation on Earth (Mount Everest, or Chomolungma; 8,850 m) to one of the lowest (Turpan Basin; 154 m below sea level). Chinese environments include some of Earth’s For general queries, contact [email protected] © Copyright, Princeton University Press.

Habitats range from tropical to boreal forest, and from extensive grasslands to desert (see the habitat images, map 1, and map 2). This wide variety of habitats has contributed greatly to the richness of China’s mammal fauna. Additionally, the geographic location of China, at the suture zone between the Palaearctic and indo-Malayan biogeo- graphic regions, further contributes to the country’s mammal diversity. overall, more than 10 percent of the world’s species of mammals live in China (556/5,416); an additional 29 species of cetaceans live in offshore waters (see Appendix i).
